Christmas trees, also known as evergreen trees, are native to regions of the Northern Hemisphere, including North America, Europe, and Asia. The most commonly used species for Christmas trees include fir, spruce, and pine trees, which all have long-lasting needles and sturdy branches that can support the weight of ornaments and other decorations. The trees are typically cut down in the fall and then transported to Christmas tree farms or lots, where they are sold to consumers. Some people also choose to buy living trees that can be replanted after the holidays.
